Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-06-01T20:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-06-01T20:00:00-CME-001 (version 5)
Source Location: S20E21
Active Region Number: 13697
Note Keyword:
DPL: CME exhibits dimpled front
GAP: Data gap
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
DIM: Dimming
Morphology Keyword:
O: Other
Note: A CME to the SE with a complex uneven (pointy) front that comes on the heels of and overlaps with the preceding 2024-06-01T19:12Z halo CME (which was concluded to be backsided). The source of this, likely front-sided, CME could be the M7.3 flare from Active Region 3697 (S20E21) peaking at 2024-06-01T19:40Z and an associated eruption signified by post-eruptive arcades and a somewhat more eastern, not very deep, dimming centered very approximately around (S20E25). The front (e.g. the width) of this CME is not easy to determine because of the overlap with the preceding, likely backsided, halo and because the CME is partially obscured by the pylon in C3.

A very uncertain analysis is based on the source location of the dimming associated with the flare and on the fit with one coronagraph (SOHO) since in STEREO A COR2 the CME is fully covered by the night time data gap. The shape of the CME front, as it is seen overlapping with the preceding, likely backsided, halo, is very complex and the exact width is hard to determine. There also can be a range of possible longitudes (at least from -20 to -25 degrees), from the longitude of the associated flare to the more eastern longitude of the associated dimming. |
